Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 5.1mm Minimum Diameter x 10mm Reach x R0.2

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise internal work and versatile turning tasks. With a 5.1 mm minimum bore diameter, a 10 mm reach, and an R0.2 nose radius, it’s engineered for small-diameter holes and tight tolerances. This tool is ideal for engineers, machinists, tradespeople, and hobbyists who need reliable performance in constrained spaces.

Two advanced PVD-coated grades give you the right performance for different materials and speeds. The BXC grade uses a TiN coating optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade is a sub-micron, triple-coated option that delivers excellent heat resistance and smoother cutting across a broad material spectrum, making it a general-purpose choice for demanding tasks.

• Coated carbide versatility for multiple materials: Two premium coatings provide tailored performance—BXC TiN for low-speed stainless work and BMK’s triple-coated, high-heat capability for broader material use and smoother cuts.
• Compact, rigid boring geometry with precise nose radius: Solid carbide construction delivers stiffness and stable cuts in small-diameter bores, with a 5.1 mm minimum diameter, 10 mm reach, and an R0.2 nose radius for tight tolerances.
• Designed for boring with turning flexibility: Optimized for boring, yet capable of general turning tasks, offering reliable, consistent results across applications and materials.

The Carmex Carbide Tiny Tool helps you achieve accurate bore sizes, smooth finishes, and longer tool life, even under demanding conditions. It supports efficient workflows, reduces downtime from tool chatter, and delivers dependable performance across stainless steels and other materials—so you can complete projects with confidence and precision.
